eufy Security T8172 eufyCam S4 2-Camera 4K Solar PTZ Security System

If you need to monitor areas such as a driveway, backyard, garage, or package drop-off, the eufyCam S4 2-Cam Kit pairs a wide scene view with a movable camera that can follow activity. Each unit combines an upper 4K bullet camera with a lower 2K PTZ camera, so one installation can capture the broader area and closer details.

For monitoring one key spot, a fixed camera may be enough, for activity moving between areas, this kit adds PTZ tracking and cross-camera handoff through the included HomeBase S380.

Worth noting

The bullet lens provides a 130° view, while the PTZ lens can rotate, track, and zoom with 8× hybrid zoom. AI features identify and track people, vehicles, and pets, and radar plus PIR motion detection helps trigger alerts. For night monitoring, spotlights support color night vision. Red and blue warning lights and a 105 dB siren provide an additional deterrent when activity meets the configured detection zone or schedule.

The two cameras connect through Wi-Fi and use a dual-antenna design. SolarPlus 2.0 and detachable solar panels support outdoor placement without hardwiring, while the included rechargeable batteries provide a battery-powered setup. The HomeBase S380 stores footage locally on its built-in 16GB drive, with expansion available up to 16TB using a 2.5-inch drive. The system works without a monthly subscription. Buyers often praise the video quality and setup experience, feedback on motion tracking, Wi-Fi, and battery performance is mixed.

Tips for day-to-day use

Position the fixed lens to cover the main approach and aim the PTZ lens toward the area where closer tracking matters. For quicker tracking response, the manufacturer recommends pointing the PTZ toward the priority area. Place each solar panel where it receives direct sunlight without shade, and adjust its orientation and tilt for the site. The cameras mount to a wall with screw-in installation. You can use the camera standalone through your router or connect it to the included HomeBase S380 for features such as cross-camera tracking and 24/7 Smart Snapshots.

Best use cases

This two-camera kit is suited to homes, sheds, rental properties, and other outdoor areas where activity may move between zones. Cross-Camera Tracking links the cameras through HomeBase S380, handing off a detected subject as it moves from one camera’s area to the other and organizing the activity into timestamped video. That makes it useful for following movement across a front yard and side yard, rather than relying on separate camera views alone.

The combination of a wide 4K view and a 2K PTZ view also suits monitoring a driveway or package area: the fixed lens captures the larger scene while PTZ tracking can follow a person or vehicle for a closer look. Smartphone control brings monitoring to a connected device, and amazon Alexa is listed as a controller option.

Practical questions

What comes in the kit? It includes one HomeBase S380, two cameras, two rechargeable batteries, two solar panels, and an instruction manual.

Does cross-camera tracking work with the included hub? Yes. Cross-Camera Tracking requires HomeBase S380, which is included with this kit. The hub links the two cameras for tracking between their coverage areas.

Can the cameras record continuously? 24/7 recording is supported when a camera is connected to direct power using a 5V/2A or higher adapter. Recording requires storage, such as a microSD card or hard drive, HomeBase 3 use requires the listed compatible software versions.

Should you buy it?

Choose the eufyCam S4 kit when outdoor monitoring calls for both a broad view and AI-assisted close-up tracking, especially across more than one property zone. Solar-supported, wire-free camera placement, local HomeBase storage, and the included two-camera setup make it a practical fit for following activity around a home, shed, or rental property without a monthly subscription.
